This one took me a really long time. I am interested in knowing the intended solving path of it to see whether I missed something.

Nice one! Tough but fair.

Finally got through this one after the video posted. Was very frustrating because as I was following the video, it was just over and over “Yeah, I got that. Yeah, I got that. I know, I already did that, *why* can’t I move forward?” Eventually just as a simple elimination, one digit got removed from a box I hadn’t removed that digit from. Stopped the video and looked at it.

Stupid math errors.

Turned out there were two clues where I just flat out botched the math, and had the wrong set of numbers I was trying to work with. Definitely makes it harder to solve a puzzle when you’re doing math wrong.
